[lib/grpc] Add support gRPC

[gnh1201]

Summary

We have decided to participate in an open-source competition hosted by the South Korean government for WelsonJS. We have noticed significant interest from the private sponsors of the competition in the gRPC protocol and their desire to utilize it for cloud resource and monitoring purposes.

Taking this into consideration, during the competition, we plan to showcase WelsonJS's original purpose as a metric information collector for Windows systems, as well as its capability for remote command execution.
